A. Rheumatoid arthritis
B. Gout
C. Osteoarthritis
D. Bursitis

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the condition characterized by the deposition of uric acid at the joints. This involves identifying the correct disease from the given options.

2. **Evaluating the Options**:
- **Option 1: Rheumatoid Arthritis**: This is a chronic inflammatory disorder affecting multiple joints but is not caused by uric acid deposition. Therefore, this option is incorrect.

- **Option 2: Gout**: Gout is indeed caused by the deposition of uric acid in the joints. It occurs due to hyperuricemia, where there is an excess of uric acid in the blood, leading to its accumulation in the joints. This option is correct.

- **Option 3: Osteoarthritis**: This type of arthritis occurs when the cartilage at the ends of bones deteriorates. It is not related to uric acid deposition, making this option incorrect.

- **Option 4: Bursitis**: This condition involves inflammation of the fluid-filled sacs (bursae) that cushion the joints and is not associated with uric acid deposition. Thus, this option is also incorrect.

3. **Conclusion**: After evaluating all the options, the correct answer is **Gout**, as it is the condition specifically associated with the deposition of uric acid in the joints.

### Final Answer:
The deposition of uric acid at the joints is known as **Gout**.
